This invention relates to improvements in mechanical toys of that typein which movement is imparted to configurations of livmv beings by powerderived from the action wheels that roll upon the ground and whichail'ord support for said configurations.

An illustrative embodiment of the invention is shown in the accompanyingdrawing in which is characterized a dog in pursuit of 1G a rabbit, andin which mechanism is-shown whereby lifelike movements are imparted tothe-configurations from the ground wheels Fig. 1 is a plan view of aform of the invention;

Fig. 2 is a side elevation projected from Fig. 1;

3 is a detail showing the crank-shaft for one pair of the ground-wheels,the frame in which the shaft is mounted, and the pitman for actuatingone of the configurations;

Fig. i is a detail view, in cross section showing one of theconfigurations and the operating mechanism therefor; and

Figs. 5, 6, 7 and 8 are side elevations illustrating respectively thesuccessive stages in the movement of the other configuration which aresequential to the position of the same configuration shown in Fig. 2.

In the illustrative embodiment there is shown a carriage frame 1 mountedupon axles 2 and 3 hat are provided at their outer ends correspondinglywith wheels 1-5 upon which the carriage may be propelled upon theground.

The rear end of the frame 1 is bifurcated,

each arm 6 being provided with an upright 7 having forwardly andrearwardly extending branches 8 and 9 which constitute a support for oneof the configurations, such as of a dog. Said configuration consists ofa body portion 10 having pivoted therein fore and rear le s 11 and 12respectively, the pivots being indicated by 13 and 14: upon which saidlegs have hinged movement. The forelegs have pivots 15 that extendthrough slots 16 made in the forwardly extending branches 8 on theuprights 7 in which they have play in the direction of said slots to anextent limited by the lengths of said slots. have pivotal connectionsrespectively with The rear legs 1930. Serial No. 449,179.

the rearwardly extending branches 9 on the uprights 7 as indicated by 17said pivots being loosely fitted in the legs or the branches so as toafford limited play relatively between said legs and branches aside fromthe axial 65 movement of said legs with respect to the axis of saidpivots. Said rearwardly extend- I ing branches 9 are each provided withshoulder or point 18 that has contact with the pivot 14 that connectsthe rear legs with the body 10 so as to retardmovement of said pivot ltin its movement about the axis of the pivotal connections 17.

The axle 2 has formed therein a center crank 19, and on saidcrank isconnected at one of its ends a link 20. The opposite end of the link ispivotally connected with the body 10 as indicated by 21, so that as theaxle 2 is rotated, vertical reciprocating movement is thereby impartedto said body.

The axle 3 also has formed therein a center crank 22 upon which ismounted a pendant extension 23 on the body 24 of another configuration,as of a rabbit. Said body 24 and its extension 23 are integral and movepivotally upon the crank 22. The forward end of the carriage frame 1 isbifurcated, and the extension 23 is disposed between the arms 25, and insaid arms are transversely secured a pair of pins 2626 spaced apart andwhich extend in a plane above the axle 3 across the path of the pendantextension 23. The spacing between said pins is such as to permit limitedplay of said extension therebetween. The rear face of the pendant 23 hasan irreg ular surface including an outwardly extending shoulder or point27 that has contact with the pin 26 during the cycle of movement of saidextension causing accelerated movement to be imparted to the body 2 1.

When the carriage is drawn or propelled upon the ground theconfigurations are actuated. The body 10 is moved upwardly by the link20 during the upward throw of the crank 20, and during the first portionof its upward movement the body swings upon the pivot 14. During thelatter portion of the upward throw of the crank 19, the body 10 tiltsupon the pivotal connection 21 with the link so that the rear end of thebody is elevated and the pivot 14 is moved over the shoulders 18 againstwhich said pivot bears momentarily. During the downward throw of thecrank 19 the body 10 is tilted upon the axis of the pivot 14 during thefirst portion of the downward throw, while the rear end of the body isdetained in elevated position through int-erfe ence of the shoulders 18with the pivot '14. As the downward throw of the crank 19 is completedthe body 10 tilts upon the pivotal connection 21, which movement is-acee11tuated when the pivot lei slips from contact with the shoulders18 permitting the rear end of the body to fall. During.thecycle-ofactionof the body 10, the front and rear legs 11 and 12 are oscillated upontheIlXQS OILillGll pivotal connections '15 and ;17.1'espect'vely so thatthe legs are first cxtcnced outwardly in opposite directions andsubsequently swung inwardly to the point of commencement, In

thismanner the configuration for ied by the body 10 and legs 1112characterizes the lifelike action of an animal in pursuit.

During the upward throw of the crank the irregular surface on theextension 23 ofthe body 24 is stroked againsttherearinostpin 2Gwhich-causes the body .24 "to pitch forwardly until the extcnsioinhascontact with the foremostpin 26, andmluringthe downward throw of thecrankr22 the:thrustiofathe extension against the foremost pin 26 causesthe body 24 torcactand swing rearwardly upon the axis of the cranktolthepositionaat the commencement of its cycle. of movement.

The action thus imparted'to"the'confignration, consisting of the bodyi24and-.itszextension characterizes the lifelike :a-ctionrof an animalpursued.
